Things to watch (4)
From the version posted Oct 22, 2026.
- Worth checking: Planned as unrestricted competition. No small business set-aside is planned, so a small business will compete against firms of any size.
- Worth checking: Specialized equipment work on an operating powerhouse. The job combines designing and manufacturing digital excitation systems with removal, installation, commissioning and model validation tests. Few small firms can cover all of it alone.
- Minor: RFP and proposal due dates are only planned. The RFP is expected in early November 2026 and proposals in early December 2026. SAM.gov's November 6, 2026 date is the presolicitation response date, so check SAM.gov for the real proposal due date.

- Minor: Optional collector ring refurbishment. Refurbishment work is done only if the Government approves it, so price it as an option that may or may not be ordered.
